Hello, I would like to know if it is possible to configure a password that expires, once user has logged, after 2 hours, for example. Thanks.

udev on CEntOS7 - can't get a match, looking for tips...
by John H Nyhuis 30 Oct '19

30 Oct '19

The mtx binary requires my tape library to be assigned a sg# driver, but the kernel periodically renumbers the sg devices. Normally, we would write a udev rule to manually assign a persistent name, but it looks like things have changed as I can't seem to get a match on CEntOS7. I'd appreciate any feedback or pointers to help me get my rule working. My two attempts are below. cat /etc/udev/rules.d/90-local.rules KERNEL=="sg[0-9]*", SUBSYSTEM=="scsi_generic", \ ENV{ID_SERIAL}=="1QUANTUM_D0H0112430_LLA", SYMLINK+="sg8" SUBSYSTEM=="scsi", SUBSYSTEMS=="scsi_genric", \ ATTRS{model}=="Scalar i40-i80 ", SYMLINK:="sg8" Neither rule above generates a match with udev, so I still have something wrong. Right now the assignment is sg7 (but it's had other names in the past. udevadm info --query=all --name=/dev/sg7 P: /devices/pci0000:00/0000:00:07.0/0000:04:00.0/0000:05:00.0/0000:06:00.1/host8/rport-8:0-0/target8:0:0/8:0:0:1/scsi_generic/sg7 N: sg7 S: tape/by-id/scsi-1QUANTUM_D0H0112430_LLA E: DEVLINKS=/dev/tape/by-id/scsi-1QUANTUM_D0H0112430_LLA E: DEVNAME=/dev/sg7 E: DEVPATH=/devices/pci0000:00/0000:00:07.0/0000:04:00.0/0000:05:00.0/0000:06:00.1/host8/rport-8:0-0/target8:0:0/8:0:0:1/scsi_generic/sg7 E: ID_MODEL=Scalar_i40-i80 E: ID_MODEL_ENC=Scalar\x20i40-i80\x20\x20 E: ID_REVISION=190G E: ID_SCSI=1 E: ID_SCSI_SERIAL=QUANTUMD0H0112430_LLA E: ID_SERIAL=1QUANTUM_D0H0112430_LLA E: ID_SERIAL_SHORT=QUANTUM_D0H0112430_LLA E: ID_TYPE=generic E: ID_VENDOR=QUANTUM E: ID_VENDOR_ENC=QUANTUM\x20 E: MAJOR=21 E: MINOR=7 E: SUBSYSTEM=scsi_generic E: USEC_INITIALIZED=28815292891 Assigned and parent device listed below: udevadm info -a -p `udevadm info -q path -n /dev/sg7` looking at device '/devices/pci0000:00/0000:00:07.0/0000:04:00.0/0000:05:00.0/0000:06:00.1/host8/rport-8:0-0/target8:0:0/8:0:0:1/scsi_generic/sg7': KERNEL=="sg7" SUBSYSTEM=="scsi_generic" DRIVER=="" looking at parent device '/devices/pci0000:00/0000:00:07.0/0000:04:00.0/0000:05:00.0/0000:06:00.1/host8/rport-8:0-0/target8:0:0/8:0:0:1': KERNELS=="8:0:0:1" SUBSYSTEMS=="scsi" DRIVERS=="ch" ATTRS{rev}=="190G" ATTRS{type}=="8" ATTRS{scsi_level}=="4" ATTRS{model}=="Scalar i40-i80 " ATTRS{state}=="running" ATTRS{unpriv_sgio}=="0" ATTRS{queue_type}=="none" ATTRS{iodone_cnt}=="0xe2" ATTRS{iorequest_cnt}=="0xe2" ATTRS{queue_ramp_up_period}=="120000" ATTRS{device_busy}=="0" ATTRS{evt_capacity_change_reported}=="0" ATTRS{timeout}=="0" ATTRS{evt_media_change}=="0" ATTRS{ioerr_cnt}=="0x7" ATTRS{queue_depth}=="30" ATTRS{vendor}=="QUANTUM " ATTRS{evt_soft_threshold_reached}=="0" ATTRS{device_blocked}=="0" ATTRS{evt_mode_parameter_change_reported}=="0" ATTRS{evt_lun_change_reported}=="0" ATTRS{evt_inquiry_change_reported}=="0" ATTRS{dh_state}=="detached" ATTRS{iocounterbits}=="32" ATTRS{eh_timeout}=="10" Would anyone mind pointing out the error in my udev rule or proposing a better way of getting a persistent sg device name? -- Thanks in advance, John H.

NFS shutdown issue
by Darby Vicker 29 Oct '19

29 Oct '19

Hi all, I have an odd interaction on a CentOS 7 file server. The basic setup is a minimal 7.x install. I have 4 internal drives (/dev/sd[a-d]) configured in a RAID5 and mounted locally on /data. This is exported via NFS to ~12 workstations which use the exported file systems for /home. I have an external drive connected via USB (/dev/sde) and mounted on /rsnapshot. I use rsnapshot to back up the RAID5 to the external drive periodically. I also export /rsnapshot (read only) to the workstations so users can grab a backup copy of /home data if needed. These two mounts (/data and /rsnapshot) should be independent of each other. However, a couple of times now I've had somebody accidentally unplug my backup drive (sde), which causes NFS to shut down. Here are the messages entries when this happens. Oct 28 16:34:12 linux-fs01 kernel: xhci_hcd 0000:00:14.0: Cannot set link state.

CentOS 8 apcupsd or nut and duplicity
by Ian P. 28 Oct '19

28 Oct '19

Hello Again, Is there any update on nut or apcupsd for CentOS 8? Also, I noticed that duplicity is not currently available for CentOS 8. I got the Fedora 30 SRPM for duplicity to build on CentOS, but ran into a dependency issue and cannot find python-devel. Any suggestions on alternatives or how to get duplicity going on CentOS 8? Cheers, Ian P.

Centos 8 Mate?
by Frank Cox 28 Oct '19

28 Oct '19

Without wanting to sound too pushy, I'm wondering if there is any update on the status of Mate now that Centos 8 has been released? I would love to jump on C8 and start playing with it, but the lack of Mate is kind of a showstopper for me at the moment. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

I think you need to give a lot more explanation on what is going on because I (at least) have no idea how you are using a non-shipped text editor . Usually if a tool is not giving similar results... I usually start by setting up a new account and unset all SHELL variables in said account. I then see if the problem occurs. If it doesn't, I make changes one by one from the other shells variables to see if it does. [Well I probably do the Wise Old Owl from the tootsy pop commercial.. once I hit three I start moving files until I get it.. sometimes it turns out that it is some weird config setting I didn't know in a file I didn't think would affect things.] I am going to expect that TERM=DUMB might be the problem.. but not sure. > _______________________________________________ > CentOS mailing list > CentOS(a)centos.org > https://lists.centos.org/mailman/listinfo/centos -- Stephen J Smoogen.

HW update. Fedora 30 to Centos?
by Dave Pawson 26 Oct '19

26 Oct '19

Due hardware update. Many years on Fedora, would like to swap out to AMD motherboard( x570) and graphics (RX480) I'm led to believe that Fedora Linux is too 'new' for Centos. Question for those with experience of both, what will I miss on Centos wrt Fedora? Not all that bothered about being 'up to the minute', and after 20+ Fedora installs it does get to be a drag... Has anyone here any 'real' drawbacks please? I'm not a power user, not a games player, just fancy a change to AMD hardware regards -- Dave Pawson XSLT XSL-FO FAQ. Docbook FAQ.
